Water4Gas Scam? Not really.

If this is as far as you have delved into the field, it is a reasonable reaction. Because if all you do is the above, you will get no other result. Anyone selling you just an HHO generator to increase your gas mileage is telling you a half truth and it will appear to be an outright lie.

THE DATA:

So how do you increase your gas mileage?  You must reduce the amount of gas being pumped into your engine. How do you do that? There are two common ways to do this. Both have to do with the Oxygen Sensor(s) of your car. (We’ll call it an O2 sensor in this article)

The O2 sensor’s function is to monitor the chemical make up of the exhaust fumes and send a signal to the On-board computer. The computer reads this voltage signal and makes adjustments to maintain a 14.7 to 1 air to gas mixture.

The O2 Sensor has two goals:

1. Help the engine run efficiently, but more importantly
2. Maintains a low level of emissions. 

The current EPA laws give a standard that must be met to market a car.  The 14.7 to 1 ratio is richer than needed for good performance. The unburned fuel is used in the catalytic converter to maintain a fire which burns the remaining emissions. When the engine runs with the optimum mixture, there is not enough fuel to maintain combustion in reaction with the catalytic converter. There's the trade off the manufacturers have to live with.

When HHO is introduced into the fuel mixture, a cleaner burn of the fuel occurs, producing a lean read at the O2 Sensor. The computer adjusts the fuel injectors to compensate for the "lean mixture" and your gas mileage drops.

How do you get the computer to adjust to this new, clean fuel?

THE SOLUTIONS:

There are two common methods to alter the O2 Sensor signal:

1. Alter the O2 sensor’s ability to analyze the exhaust.
2. Alter the voltage signal from the O2 sensor to the computer.

Update: Another method being tested is to change nothing. It has been stated that if you drive your car for 6 weeks, the computer will adapt to the new fuel and you will see improved mileage. This was tested on a 2 liter Ford Focus. The generator was producing .6 liters per minute at 14 amps. The mileage dropped from 27 to 24 for the first two weeks, but on the third week was back up to 27 mpg. The mpg slowly climbed each week there after, getting to 27.9 mpg on the 6th week. Not a spectacular result, but the car had better mileage and you could smell no fumes from the exhaust.

Altering the O2 Sensor:

• A common method is to lift the O2 sensor out of the exhaust stream, using an O2 Sensor extender.  Another method recommended by some booklets is to wrap the O2 Sensor with aluminum foil. Both methods have limited workability. There are also reports of the aluminum foil "disappearing". Based on the heat and fast flow of exhaust gases, this is not surprising.

Altering the O2 Sensor Signal Electronically:

• The second and better method is accomplished with an O2 Sensor voltage adjuster, also known as an EFIE, Electronic Fuel Injection Enhancer. The EFIE is an electronic device placed between the O2 Sensor and computer. The EFIE is manually adjusted to enforce a leaner mixture.

One of the benefits of an EFIE is that it can be on the same electrical circuit as the HHO generator. If you turn  off your HHO Generator the O2 sensor signal reverts back to its original operation.  If you lift your O2 Sensor, and stop running your HHO Generator, you could run your car too lean and possibly damage it.

It may be easier to take a short cut using extenders or aluminum foil, but for the best result go with an EFIE.
